I don't have the part number. I've only had one other bike that came with a jap carburettor. It promptly fell apart, so I tossed it and got an S&S. Have I ever mentioned that I am not terribly impressed wit Japanese "quality"? If I ever come across a US or UK made carb that will fit this engine, I will do anything necessary to change over.
